We have had a good number of MassSave energy audits in the past. Recently we had an audit done by Adam Zwick. I would definitely say that Adam did by far the most thorough inspection of our house including attic, basement, etc. He did not shy away from getting into tight spaces and getting loose insulation on himself. Thanks to his work we are scheduled for some significant upgrade to our home energy efficiency. Again, Adam was 10 times more thorough in his inspection than previous auditors all while being professional, courteous , and leaving things very clean. Highly recommended!
